Assertion (A): The enthalpy of formation of H_(2)O_((l)) is greater than that of H_(2)O_((g)) Reason (R ): Enthalpy change is negative for the condensation reaction H_(2)O_((g)) rarr H_(2)O_((l))

Answer»

A and R are true, R explains A
A and R are true, R does not explain A
A is true, but R is false
A is false, but R is true

Solution :`DELTA H_(f(H_(2)O)_(g)) = Delta H_(f(H_(2)O)_(f)) + Delta H_("vap")`
